95% of all hydrogen produced globally is derived from fossil fuel sources with the balance produced from renewable sources including the electrolysis of water.
This is due to sustainable/renewable methods being by order of magnitude, more expensive. Modern water electrolysis technologies rely on the use of membranes or diaphragms to provide a means of separating the produced constituent gases. Issues pertaining to reliability, operating parameter thresholds and expensive materials of construction due to the inclusion of membranes/diaphragms impedes the absorption of these technologies into industry. DEFTTM alkaline electrolysis does not utilise conventional diaphragms and membranes, and hence provides significant potential to generate a low CAPEX and OPEX design.
